beyondjs/specifier-parser

`@beyond-js/specifier-parser` is a TypeScript utility library that parses, validates and serialises module specifier strings (package name, scope, version and sub‑path) for use in the BeyondJS framework and any TypeScript/JavaScript project that needs robust handling of import specifiers. It exposes a `PackageSpecifier` class with properties like `pkg`, `version`, `subpath`, and `valid`, making it useful for developers building or extending BeyondJS‑based modular applications or any tooling that works with npm‑style package references.
